Computational Geology is a spreadsheetintensive, geological-mathematical problemsolving course recently developed at the University of South Florida. Requested by nontraditional students and now a required part of the geology curriculum, the course finishes off the required calculus sequence and its prerequisites. It makes connections between the various strands of mathematics and between mathematics and geology. It aims to enhance mathematical literacy and computational skills and to improve the mathematical comfort level of our students. It also promotes a mathematical problem-solving disposition that is useful to students regardless of whether they remain in geology.
